3 Claims.

The object of my invention is to provide a wringer structure emespecially sensitive mechanism by which quickly released and resetrelative to its spring mounting. and improved means by which the rangeof available spring pressure may be varied.

The accompanying drawings illustrate my invention:

Fig. 1 is a fragmentary front elevation. in partial vertical section, ofan embodiment of my invention;

Fig. 2 is a fragmentary end elevation;

Fig. 3 is a section on line 3-3 .of Fig. '1;

Fig. 4 is a fragmentary section on line 4-4 of Fig. 1;

Fig. 5 is a fragmentary front elevation, in partial vertical section, ofanother embodiment of my invention;

Fig. 6 is a fragmentary end elevation, in partial vertical section, ofthe structure shown in Fig. 5;

Fig. 'l is a parts of the wedge-adjusting means;

Fig. 8 is a section of another form of adjustable abutment for thepressure spring; and

Fig. 9 is a section of line 3-9 of Fig, 8.

Referring first to Figs. 1 to 4, l0 indicates the main base structure ofthe wringer which imcludes the hollow end standards II, II in whic aremounted the bearing blocks l2, l2 and l3, l3, respectively, for thelower roller l4 and the upper roller 15.

The base structure is supplemented by the upper frame bar, or bridgebar, l6, which is U- shaped in transverse section and within which ismounted the spring H, the ends of which act uponthe bearing blocks l3,l3 to yieldingly urge the upper roller toward the lower roller.

The bridge bar it at one end is pierced at It to receive, and verticallyand transversely interlock with, a pin l9 carried by one of thestandards ii near its upper end.

Pivoted at 20, on the opposite end of the bridge bar is a dependinglever 2| which is connected to the adjacent standard II by the togglelink 22 pivoted at 23 to the standard II and at 24 to the lever 2i.

Pivoted at 30 within standard II, on an axis parallel with the axes ofthe rollers l4 and I5, is a T-shaped lever 3!, the head arms areprojected laterally in the upper end of the standard ii. The oppositelyprojected ends of the heads of this lever carry individualhand-manipulable plates 32.

the pressure roller may be of which 50 drawings to which furtherreference may be made, lever 3| may be duplicated in the other standardII and connected by plates similar to plates 32 but of lengthssufficient to extend from one standard I l to the other.

The lever 3| adjacent lever 2| is provided with 9. depending arm 3|notched at II" to form a pair of diverging camming surfaces whichnormally straddle the ridge 32 of a latch lever 33 pivoted at 34 on thbase and urged to latching position by spring 35 interposed between thebase and the latch. Latch 33 is provided at its outer end with anupturned tip 36 adapted to engage and retain the camming finger 31carried by lever 2| near its free lower end.

The spring I1 is carried by a clip 40 havin depending perforated endears ll through which fragmentary horizontal section of the spring isprojected. Clip 40 is provided with upstanding side ears 42 betweenwhich are journalled rollers 43. Journalled in pocket 44 and bracket 45,within bridge-bar I6, is a shaft 46, which is projected through clip Illand spring l1, and this shaft is provided with a pinion 41 and apolygonal portion 48 upon which is sleeved the knurled operating disk49, the periphery of which projects through slots 50 in the side wallsof bridge-bar I6. Secured to the side walls of bridge-bar it are tracks5|, and a wedge 52. which is medially slotted at 53 and provided alongone side of the slot with rack teeth 54 which' mesh with pinion 41, isinterposed between these tracks and the rollers 43.

By rotating disk 49 wedge 52 may be adjusted. relative to clip 40, toadjust the effect of spring II when the bridge-bar is forced down tooperating position by manipulation of lever 2|.

In Figs. 5 and 6 the bridge-bar release mechanism is of the same generalcharacter but differs slightly in form so that the lever 2l0 (theequivalent of lever 2|) is partially nested within the standardportion'of the base structures.

through appropriate slots In this form, one of the end standards III! ofbase Hill is vertically slotted at ill to receive lever 2lll pivoted at200 to bridge-bar I60 and connected by toggle link 220 with base I03.The latch 330, provided with cam ridge 330' is provided with adown-turned tip 360 engageable by the finger 310 carried by lever 2lll.A lever 3lll (like lever 3i) is pivoted within each standard H0 and thenotched lower arm 3H) of one of the levers straddles ridge 330.

The heads of the two levers3lll, on opposite sides of the wringer, areconnected by the plates 320 which extend across the faces of the struclfdesired, as indicated in other figures of the 55 ture parallel with therollers.

In Figs. .5 and 6 the end standards of the main frame are drawn in so asto form a shoulder" and upwardly projecting flange 8| so as to form aguide and seat for the bridge-bar I". thus facilitating the readyreplacement of the brldIebar after the quick-release mechanism has beenmanipulated. W

In Figs. 8 and 9 the spring I1 is projected through a sheet metal boxingl securggLwithin bridge-bar I6 and carries a clip ll provided with aroller 12 which abuts a wedge l3 slldably mounted between the u bar andtracks H. The upper wall of the bridgebar is longitudinally slotted at Iand this slot is covered by a plate which, together with an accessiblefinger piece 16,-is secured to wedge 13 so that the wedge may be readilyadjusted to change the pressure which may be exerted by the spring uponthe wringer rollers when the bridge-bar is forced to operative position.

In the form shown in Figs. 1 and 2, pressure or pull'oneither plate 32serves to withdraw latch 33 from finger 31 so as to relieve the upperroller from spring pressure, and similarly, in the form shown in Figs. 5and 6, pressure or pull on either bar 320 will withdraw latch 330 so asto relieve the upper roller from spring pressure.

It will be noted, by referring to Fig. 1, that when the toggle lever,formed by the links 2|, 22, is moved to the position to be retained bylatch 33, the pivot 24 falls short of the plane of pivots and 23 sothat, if the rollers Hand I5 and the spring I! be in position, thetoggle lever will be under some stress from spring I! so that, when thelink 2| is released by withdrawal of latch 33 from spring 31, links 2land 22 will be swung toward the right about their respective pivots 20and 23.

The same is. true of the structure shown in Fig. 5 where the links areH0 and 220'respectively, the latch is 360 and the finger is 310.

I claim as my invention:
